Union as a Memory View

Union as a Memory View

Implement a union that lets you view a `uint32_t` as its individual bytes, and a function `get_byte` that extracts the nth byte (0 = least significant).

typedef union {

uint32_t word;

uint8_t bytes[4];

} WordView;

Why it matters: This pattern is everywhere in embedded — reading sensor registers, parsing CAN frames, interpreting protocol headers.
